We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi Metodi Belchovski,

Thank you for the post. The central frequency doesn't really affect the PD responsivity since the frequency dependency of responsivity is defined in the user defined table. The responsivity is based on the input optical signal power.Â
